Weekly Riddles

Description: Well, as the title says, I shall attempt to post a new riddle every week, and whoever guesses correctly (WITHOUT LOOKING UP THE ANSWER) shall get ... a congratulations and a cyber-pat-on-the-back from me. And in the more than likely chance that I miss a week, I shall post two new riddles the next week and give you all permission to throw rocks at me. ... o.O ... Okay, why don't we go with dirtclods, then?

Rules:
-I'll post a new riddle every Wednesday.
-You each get one guess per week, so choose wisely.
-Word-play riddles shall be written how they originally sound, as in I shall not reveal the answer by writing the words correctly.
-If I make a typo in anything, please inform me so I may correct it.
-You can reply with your answers.
-I'll announce the correct answer to last week's riddle, accompanied by the new riddle for the week.
-I'll be keeping score and I'll announce the person who answered right the most every three months.
-PLEASE do not look up the answers. For those who weren't planning to, I thank you. It just ruins the game if you look it up.
- If EVERYBODY gets a relatively hard riddle right, I WILL suspect something! -Looks left, looks right-

This Week's Riddle:

What is the next letter in this series? - OTTFFSSE

Answer to Last Week's Riddle:

It says "imagine" you are in a car and can't get out. So, how do you get out? Simple. You stop imagining.

Any random babblings I want to add on in case someone actually took the time to read this far:

... Wow ... O.O It's been a little short of a year since I last posted. Please do throw rocks at me.

Is it...a person holding a deck of cards?

They have a knight with them

well if I can fit 9 people in a 5 seater car...

What is greater than God, more evil than the Devil, the poor have it, the rich need it, and if you eat it you will die?

Nothing.

nothing. Ive heard it before, but its still awesome

well, normally i'd agree with them and say it's nothing, but that if you drink it you die thing just stumps me. hmmm. probably something like...poison? no.. waah! i dunno!

stay in there???

I think i"m gonna go ahead and state the obvious answer: E?

it is "O" because the series repeats itself, and you just named the entire series. The first letter is "O" so when it repeats itself the next letter will clearly be O
